Application filed February 9,1910. Serial No. 542,952.

To all whom it may concern: I a

Be it known that I, FRANK B. Coon,"a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvement-sin Folding Brackets, of

. which the following isa specification;

This invention relates to folding brackets support telephones, electric adapted to lights, or other articles.

One of the objects-of the invention is to provide a lazy-tongs bracket which shall have a wide bearing upon its support in all the positions which the bracketoccupies.

Another object is to produce a folding .bracket which will operate to move the supported article vertically when the bracket is extended. v

A further object of the invent-ion is to provide improved means, in a bracket of the type mentioned, for attaching the supported article to the bracket.

Another object is to provide means for supporting a telephone cord or a lamp cord upon the bracket.

In the accompanying drawings, Figure- 1 is a side elevation of'a folding bracket embodying the features of my invention,-the bracket being represented as foldedl; Fig. 2 is a top plan view of the bracket partly extended. Fig. 3 is a side elevation showing the bracket in the same position as in Fig.

2.- Fig. '4; is a side elevation ofthe bracket extended so as to elevate the supported article. Fig. 5 is a sect-ion on .line5 5 of Fig. 1; Fig. '6 is a section on line 6 6 of Fig. 3, illustrating an eye for'receiving a telephone cord or lamp cord.

Theembodiment hereinshown of my invention comprises a'suitable support and a "lazy-tongs member attached at one end to said. support, the opposite end of said member carrying means for engaging the article to be supported, as, for instance, a desk telephiiner .In the particular construction shown in the drawings, the initial extending movement of the lazy-tongs member carlies the. supported article-outward in a sub-.

stantially horizontal plane,l:'urthe1' extension of said member operating to move the article into a higherplane.

The lazy-tongs member A of the device.

maybe attached to a supporting structure in any suitable Way. Herein l have shown ita'spi-voted to swing in a horizontal. plane upon a post 1, which post is fixed in a socket member 2 by means of a set screw 3. Integral with the socket member 2 is an attaching portion 4 which may be secured to a desk, a wall, or any other suitable support. p

The lazy-tongs member A of the bracket consists of a series of diagonal levers 5, 6, 7, 8, 9 and 10, said levers being pivotally connected at their ends and at their points of intersection. It will be" understood that there may be any suitable number of the intermediate levers? and 8. The telephone. or other article'isj supported upon the free.

to the lever 7 and at its other end is pivoted to a sleeve-13 which is rotatableupon the post 1. Thesleeve 13 is herein shown as hear-- ing against the upper end of the socket-memher 2 and as being held from upward displacement by a pin 14:. A'bearing sleeve 15 of fiber or other suitable material may be interposed between the sleeve 13 and the post, if desired.

The length of the levers 5 and .6 is approximately one and one-half times'that ofthe intermediate levers 7 and'8, the point o fpivotal connection between said levers 5 and .6 beingso positio-nedas tomake the shorter arms of said levers substantially equal to the arms of the levers 7 and 8. One of the levers '5 or 6, in this instan ce the lever 5, has a joint 16 therein substantially midway of its'longer arm. It. will be seen that the points of attachment of the levers 5 and 6 to the post 1 are separated a dis tame-substantially equal to the length of one of the intermediate levers f7 and 8, whereby a wide bearing of the bracket on the post isobtain'ed with consequent stability and rigidity, even when the bracket is wholly extended. The provision of the joint v 16 in the lever.5 obviates the necessity of providing a sliding attachment between'one of the end levers ofthe series and the supporting post or standard.

The adjacent ends of the levers 9 and 10 are provided with intermeshing gear segments 17. The geared ends of the levers 9 and 10 lie between two plates 18 that are secured in place'by screws or bolts 19, which screws serve as pivots for the levers 9 and 10 and coincide with the centers of rotation of the'gear se Inents 17. 1

The teleph ne or other" article' may be attached to the bracket by means of a socket or clamp formed, in this instance, of two bent plates 20, the, attaching portions of which .plates lie in contact with the outer sides of the plates 18 and are securedto said plates by means ofthe screws or bolts 19, as clearly shown inFig. 2. The curved parts of the plates 20' forin-a socket or clamp for the reception of the stem of a desk telephone or other similar article.

In order to support a telephone cord or lamp cord I provide upon the extensible and .contractible member A- a suitable number of eyes 21. Each of these eyes preferably is made-from an integral piece of wire bent, asshown in Fig.- 6, to form a shank. 21 and .an eye portion 21 Theends of the piece of wire from which the device is formed are preferably disposed at one side of the eye portion and are separated so as to provide an entranceEZl for the cord.

In order that the eyes 21 may be convenientl'y attached to and detached from the bracket, I employ tubular rivets 22 for pivotally connecting together the ends of the levers 5 to 10. The shank 21 of an eye maybe inserted into any of the openings formedby said tubular rivets, and will be held therein by the resiliency of the material from which the eye is formed. When the cord is passed through appropriate eyes vQ21 the cord will be properly supported in' every position of the lazy-tongs member A;-

Assuming the bracket tobe attached/toa desk and usedto' support atelephone, it

will be seen that when the bracket is ex-- tended as shown in Fig. 3, the telephone will be carried out in a horizontal direction into position for convenient use a person seated at the desk. v

From an inspection. of Figs. 3 and''qit may be seen that as the bracket .is extended farther from the position shown-in Fig. 3 the joint 16 in the lever 5 moves down wardly, and said lever --begins to fold together 1n the opposite direction from that indicated in 'Fig. 1. The distance between v the sleeve 11 and the point of connection of the levers 5 and 6 is thus lessened and the.

lever 6 draw'n upwardly, thereby elevating the outer end of the bracket. In this position of the bracket, a telephone carried thereby may be conveniently used by a personin a standing posture.

The invention is notlimited to. the details shown, for various :changes will occiin to persons skilled. in the art.

I claim as my invention:

2. A folding bracket comprising a post and a lazy-tongs member, the two evers at one end of said member being attached at one end to saidpost, said end levers being substantially one and one-half times as long as the intermediate levers of said member, the pivotal connection between said end levers being so positioned as to make the shorter arms thereof substantially equal in length to the'arms of said intermediate levers, one of said end levers being jointed substantially midway of its longer arm.
